alarming rates of radioactivity even in europe

.

updated: april 29

The following map of Germany with measurements in microsievert per hour shows levels over the limit for the public of 0.11 microsievert per hour in most parts of Germany. I wrote earlier that "People living in central Europe should stay indoors: pregnant women and children OUGHT to stay indoors". Unfortunately I later on had more time to read the available data: the situation has been consistently at levels in microsievert per hour deemed high for the past 31 days. It is therefore of no use to stay indoors because indoor air after a couple of hours is completely renewed with outdoor air. On the telephone, Chris Busby of the Low Level Radiation Campaign, told this writer he thinks the levels are double what they should be and Michele Rivasi MEP Criirad said to be also worried by these figures. On the other hand Roland Desbordes from the french Criirad considers in an email, that there are no precisions about the origin and the nature of the detected radiation. Therefore the values could correspond to natural fluctuations and reflect nothing abnormal. Please give support to the call by the Criirad to make all CTBTO data available, in particular the data for Plutonium and Uranium contamination.


For a total transparency on the airborne radioactivity we are breathing (CRIIRAD)

For a total transparency on the airborne radioactivity we are breathing Fukushima (Japon)

There are 60 certified radionuclide stations fully equipped with high precision detectors that are set up around the world to monitor airborne radioactivity on a daily basis with unprecedented accuracy. Their objective : Find low quantities of radioactive particles that could reveal a possible nuclear test in violation of the Comprehensive nuclear test ban treaty (CNTBT).

Results of the analyses would allow a follow up, day by day since March 12, 2011, of the evolution on the contaminated airborne masses linked to the radioactive rejections of the FUKUSHIMA DAIICHII nuclear plant. To date this is still impossible as the data are being confiscated by the States. The results are communicated to pre selected official organizations required to keep all information away from public awareness.

This global measuring network is financed by Public funds. Populations have the right to have access to this information. All the figures without exception must be published and not just a few figures carefully selected by the authorities.

I hereby demand that the results of the analyses conducted to measure the airborne radioactivity by the global network (TICEN) be made public, ENTIRELY AND WITHOUT ANY FURTHER DELAY.

Funded by all the citizens of member states, these figures must be made available to public knowledge to serve their right to protection and safety.

...Two robots sent into the reactor No. 1 building at the plant yesterday took readings as high as 1,120 millisierverts of radiation per hour...“Tepco must figure out the source of high radiation,” said Hironobu Unesaki, a nuclear engineering professor at Kyoto University. “If it’s from contaminated water leaking from inside the reactor, Tepco’s so-called water tomb may be jeopardized because flooding the containment vessel will result in more radiation in the building.”...

Atmospheric radiation leak underestimated

Data released by the government indicates radioactive material was leaking into the atmosphere from the Fukushima No. 1 nuclear power plant in early April in greater quantities than previously estimated.

Radioactive material was being released into the atmosphere from the plant at an estimated rate of 154 terabecquerels per day as of April 5, according to data released by the Cabinet Office's Nuclear Safety Commission on Saturday.

The NSC previously estimated radiation leakage on April 5 at "less than 1 terabecquerel per hour."

Iodine-131 and cesium-137 were released into the atmosphere that day at the estimated rates of 0.69 terabecquerel per hour and 0.14 terabecquerel per hour, respectively, the NSC said.

Emissions are converted into iodine-131 equivalents for assessment on the international nuclear event scale (INES), to arrive at the total 154 terabecquerels per day, the nuclear safety watchdog said.

One terabecquerel equals 1 trillion becquerels.

On April 17, plant operator Tokyo Electric Power Co. said in its plan for stabilization of the crippled reactors it would not start to get radiation leakage under control until the plan's fourth month of implementation.

This would mean 10,000 terabecquerels of radioactive substances would be released into the atmosphere from the plant during the coming three months, according to simple calculations based on the estimated emission rate as of April 5.

Emissions in that three-month period alone would therefore exceed the level necessary for a Level 6 severity rating on the INES, the globally accepted measure for evaluating nuclear accidents.

The ongoing crisis at the Fukushima plant has been rated a maximum Level 7 on the scale, which was established by the International Atomic Energy Agency and the Organization for Economic Cooperation and Development in 1992.

The total amount of radioactive material discharged from the plant from March 11 to early April was estimated between 370,000 and 630,000 terabecquerels, according to government sources.

The commission, however, said the figures were estimates only, "with a considerable margin of error." Radiation levels around the six-reactor complex have been slowly falling, it said.
